I have just built my ender 3 v2, and started the procedure to auto home, as per the instruction manual.
No motors are working.
I have tried the z, x and extruder movement and nothing happens.
I have replaced the cables and tried various permutations.
The screen, and fan work, and the hotend comes upto temperature, but there is no bed or head movement, not extruder feeding.
I have flashed to the latest firmware, without any improvements.
What could be the problem?
Thanks in advance,
